To add to TT's last sentence: "As long as the P traps & Hepvo traps on all drains inside are working you should not get odors back inside the rv from the park system."

But you will have those sewer gasses "floating around on your roof" as they escape from the vent stacks. If you have a roof vent open, a roof vent fan pulling air out of the trailer or a leaking HEPVO or dry P trap, you will get the "sewer smell" in your trailer from the open vents on the roof as the campground sewer gasses flow up through your tanks and out the roof vents on those tanks.
